Application filed February 27, 1915. Serial No. 10,985.

' To all'whom it may concern:

Be it known that I, HnRcULEs PERVELIS, a subject of the King of Greece, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Sectional Guns, of which the following is a specification.

This invention relates to a gun composed of a series of sections with means for detachably connecting the sections together and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a structure especially adapted to be used in connection with guns of large caliber whereby a gun composed of sections is provided, the said sections being adapted to interfit with each other at their ends and means being provided for securely holding the sec tions in place with relation to each other when the gun is in use. The said sections are also detachable from each other and may be packed in compact space for transportation or other purposes.

A prime object of the invention is to provide a gun which may be easily and quickly transported from point to point over rough country due to the fact that the sections may be detached from each other and readily carried upon pack animals or other transporting means. When the component parts have been assembled at a desired point and connected together a gun of comparatively large caliber is had in a position which by reason of lack of usual approaches could not be used in military operations by reason of the impossibility to set up the usual artillery pieces and the impossibility of transporting the said pieces to the said locality.

With these objects in view the gun comprises a series of sections which interfit at their ends one with the other and which are bored at a uniform diameter. These bores register with each other when the sections are connected and constitute a complete bore for the gun. The said sections are provided at their adjacent ends with right and left screw threads and nuts of peculiar design and pattern are arranged to engage the said threads and draw the ends of the sections in close contact with each other thereby preventing the escape of gases between the Looking means are provided for holding the said nuts against turning movement when in position upon the gun sections but the said locking means are of such structure as to be readily manipulated for the purpose of releasing the nut when it is desired to disconnect the sections of the gun one from the other.

In the accompanying drawing :Figure l is a side elevation of the gun with parts in section. Fig. 2 is a side elevation of parts of the gun separated and showing portions in sections. Fig. 3 is an end view of one of the nuts with part in section. Fig. 4 is a transverse sectional view of a portion of one of the sections of the gun cut on the line ll of Fig. 2. Fig. 5 is a perspective view of parts of the nut locking means provided upon the gun section.

The gun may be composed of any desired number of sections but for the purpose of illustration a gun of three sections is shown and described. Sections of the gun are indicated at l, 2 and 3. The section 1 is the breech section, the section 2 is an intermediate section and the section 3 is the muzzle section. All of these sections are provided with a bore 4 and when the sections are connected with each other the said bores are in longitudinal alinement with each other and constitute the bore for the assembled gun structure. All of the gun sections except the muzzle section 3 are provided at their forward ends with counter bores 5 of greater diameter than the bores 4. The intermediate and muzzle sections are provided at their rear ends with bosses 6 adapted to fit snugly in the counter bores 5 as best shown in Fig. l of the drawing. The intermediate and muzzle gun sections 2 and 3 are provided at their rear ends with pins .7 which fit snugly in sockets 8 provided at the forward ends of the breech and intermediate sections respectively. The breech and intermediate sections 1 and 2 are provided at their forward ends and upon their peripheries with longitudinally disposed recesses 9 and threads 10 are provided upon the peripheries of the said sections at the portions thereof which lie between the recesses 9. The threads 10 at the opposite sides of the ends of the sections when the gun its fired.

' 10' when the sections are assembled.

recesses 9 are in spiral alinement with each other but the presence of the recesses 9 in the said threads interrupts the continuity of the same. As shown the threads 10 are right hand threads.

The intermediate and muzzle gun sections 2 and 3 are provided at their rear endswith recesses. 11 similar to the recesses 9. The sections 2 and 3 are provided upon those portions which lie between the recesses'll with threads 12 and the portions having thethreads 12 are adapted to be brought against the ends of the portions having the threads The threads 12 are disposed opposite to the threads 10 and inasmuch as the threads 10 are right hand threads the threads 12 are left hand threads. When the sections are assembled the recesses 11 are in longitudinal alinement with the recesses 9 and the pins 7 are received in the sockets 8.

Nuts 13 are provided for connecting the section 2 with the section 1 and the section 3 with the section 2 and as these nuts are of the same design and configuration a description of one will answer for both. Each nut 13 is provided at its inner side with threaded spurs 1 1 the threads upon the spurs at the opposite ends of the nuts being disposed in opposite directions and adapted to engage the threads 10 and 12 respectively. Prior to engaging the threads 10 and 12 the spurs 14: are received in the recesses 9 and 11 consequently when the nuts 13 are turned upon the sections the adjacent sections are drawn at their ends into close contact with each other. Each nut 13 is provided in its interior and between its ends with an annular cavity 15 and the said cavity fits over the adjacent ends of the abutting sections when the parts are assent bled and serves as a trap for receiving any gas that may escape between the adjacent ends of the sections when the gun'is fired. This prevents the gas from entering between threads 14, 10 and 12 and corroding or damaging the same. Each nut 13 is provided at its rear face with a series of recesses 16 spaced at regular intervals apart. Each nut 13 is provided upon its periphery with a series of teeth 17 with which a wrench (not shown) may be connected for the purpose of turning the nut. A locking device is provided upon each of the sections 1 and 2 for locking the nuts 13 in position when applied and each of said locking devices comprises a plate 18 secured to the section and having stops 19 mounted thereon. Bolts 20 are also mounted upon the plate 18 and pass through the stops 19 and a plate 21 is loosely mounted upon the bolts 20. Nuts 22 are screw threaded upon the bolts 20 and are adapted to engage at their under faces the plate 21 and hold the same in a fixed position with relation to the stops 19. Lugs 23 are mounted upon the plate 21 and a traction bolt 24: passes through the lugs 23 and is provided with a nut 25 which when tightened is adapted to draw the lugs 23 toward each other. A pin 26 lies between the lugs 23 and when the bolt 24 is tightened the said pin;26 is grasped and held against movement with relation to the said lugs. A

lever 27 is iulcrumed upon the pin 26 and is provided with a forked end 28 which engagesbehind a head 29 of a stud 30 carried by a block31. The block 31 lies between the plates 21 and 18 and when the nuts 22 are tightened upon" the bolts 20 the inter- W The block 31 is When it is desired to disconnect the sections 1, 2 and 3 from each other the nuts 22 are loosened whereby the blocks 31 are released then the levers 27 are swung so that the blocks 31 are moved longitudinally and the pins 32 are withdrawn from the recesses 16. Thus thenu-ts 13 are released and they may be turned to cause their threads 14 to disengage from the threads 10 and 12 and enter the recesses 9 and 11. When this has been done the sections may be moved longitudinally with relation to each other and disconnected from one another.

When the parts are assembled the operations above described are reversed and prior to tightening the nuts 22 the blocks 31 may be moved between the plates 21 and 18 to bring the pins 32 into desired recesses 16 and after the said pins enter the recesses the nuts 22 are tightened whereby the nuts 13 are held against turning movement upon the sections and then the nut 25 upon the bolt 21 is tightened so that the pin 26 is held against turning movement between the lugs 23. I

From the above description taken in conjunction with the accompanying drawing it will be seen that a gun of simple and durable structure is provided and the sections which composed the gun may be easily and readily detached from each other for transportation and when the said sections are brought together they may be quickly and effectually secured in position with relation to each other to permit of the use of the gun for firing projectlles 1n the usual manner.
